Timeline :  2023 - 2024

Problem Statement

Trinidad and Tobago's current postal system presents significant user experience
challenges, hindering efficient address verification, mapping, and parcel tracking.
Users, including customers, TTPost staff, and postal workers, face difficulties in finding and managing addresses, requesting official documents, and optimizing delivery routes. 

These challenges result in delayed deliveries, frustrated customers, and inefficiencies in the postal service.

TTPOST faces a pressing need to develop a comprehensive digital solution that
empowers customers to effortlessly locate their properties on a map, obtain their full S42 addresses, request address cards and submit queries, thereby streamlining the adoption of the new addressing standard and ensuring the efficient mail delivery for all TTPOST customers.


The Proposed Solution

The TTPost Suite of Applications
represents a pioneering solution that
revolutionizes address management
within the unique context of Trinidad
and Tobago. Comprising a user-
centric Customer Application, a
robust Backend Application for TTPost staff, and an innovative Postman App for postal workers, this suite addresses the challenges of Trinidad and Tobago's S42 addressing system.

Seamlessly integrating technology with the established S42 standard, these
applications empower users to effortlessly verify and manage their addresses, request official documents, and facilitate efficient parcel deliveries. Designed with a focus on user experience, data accuracy, and timely updates, the TTPost Suite of Applications emerges as a comprehensive and specialized solution, poised to elevate the efficiency and reliability of the Trinidad and Tobago postal service.


User Interviews

To gain deeper insights into the needs and pain points of potential users, a few interviews were conducted as part of the UX case study. The interviews involved individuals from diverse backgrounds, including those who have personally experienced issues with their S42 Addresses in Trinidad and Tobago. 

By conducting these interviews, valuable firsthand information was obtained, allowing for a more empathetic and user-centered design approach.

These user research interviews served as a foundation for the design process, informing the decision-making process at each stage.

Pain Points from the User Interviews


Complexity and Understanding

Users expressed difficulties in locating and managing their S42 addresses. Insights revealed challenges in understanding the new addressing standard and navigating the process of requesting official S42 Address cards.

Privacy Concerns

Users expressed hesitation towards having their address displayed on the app for public use due to security concerns.

User Experience

Users expressed confusion on the right person to contact when wanting to query their new address or express issues. Users also expressed a lack of understanding about the new format and its purpose.


TTPOST insights

In addition to engaging with potential users, meaningful insights were also gleaned through conversations with TTPost stakeholders. These discussions provided invaluable perspectives on internal processes, challenges, and opportunities within the organization. By collaborating closely with TTPost, we aimed to gain a comprehensive understanding of their operational needs and pain points, ultimately shaping a solution that addresses both user and organizational requirements.


Pain Points from conversations with TTPOST


Request processing overload

TTPost encounters a notable issue in handling a high volume of requests, especially during peak periods. The sheer number of requests overwhelms the existing processing capacity, leading to bottlenecks and delays in addressing customer needs. This challenge not only strains internal resources but also impacts customer satisfaction due to extended wait times for resolution..

Lengthy processing times

TTPost faces the challenge of extended processing times for addressing customer requests, with potential wait times stretching up to two weeks. This prolonged duration significantly impacts the responsiveness and efficiency of the service, leading to dissatisfaction among customers who expect timely resolution of their queries or requests.

Missing vital information

Many users lack familiarity with the process of obtaining geo coordinates, leading to submissions without this vital information. As a result, TTPost must invest additional effort in acquiring geo coordinates, causing inefficiencies and delays in processing requests.


User Personas

To deepen our understanding of the diverse needs and preferences of our target audience, we have developed user personas based on insights gathered from user interviews and stakeholder conversations. These personas represent archetypal users who engage with the TTPost addressing system and provide valuable insights into their behaviors, motivations, and pain points. By personifying our users, we can empathize with their experiences and tailor our solution to meet their specific needs effectively.

Maria - The busy Urban Professional

Background: Maria is a 32 year old woman
working in the heart of Port of Spain. She
works Monday - Friday and hardly gets time
off of work to conduct her personal business.
Her driver’s license has recently just expired
and she was told at the licensing office that
she needs to get the new S42 Address to
renew her driver’s license.

Goals & Needs: Maria’s main goal is to get access to her
new S42 Address without having to go into any physical TTPOST locations as she
does not have the time off of work to do so. She also needs this process to be simple and fast as she does not have the time to spend to go through multiple exhausting steps just to access the information. Maria would also like to apply for the official card so that when presented with this issue at a later date, she would not have to go through this process again to access her S42 Address.

Challenges: Limited free time as she works Monday to Friday and it is very difficult for her to get time off from work to conduct her personal business. She does not have the time to fill out forms, submit and wait for approval to get her information, she is in need of information more immediately.


Kevin- TTPOST Overworked Admin Staff

Background: Kevin is a 40 year old TTPOST
Admin staff who is always busy and overworked due to
his department being understaffed. His role is to
manage and update address data as well as process
address card requests. He is often found prioritising the
address management and updating over the address
card requests due to the fact that these requests are
done on paper and are not easily or quickly processed.
This results in Kevin not meeting his KPIs and his boss is becoming frustrated with him.

Goals & Needs: Kevin needs a way to simply and quickly process address card
requests with as little effort as possible to be able to meet his KPIs. He also needs a
way to ensure that the addresses being provided to users are as accurate as possible and that the process of exporting the data and importing the data into another system for TTPOST customers is as seamless as possible to ensure he can perform his job
more efficiently.

Challenges: Kevin struggles with juggling all his tasks in a fast paced environment and meeting his KPIs. He also struggles with balancing data accuracy with efficiency. Kevin often experiences a lot of angry customers calling him to check on the status of their address card requests and it takes a toll on his mental health.

Competitor Analysis

Comparing the TTPOST suite of applications to popular Mapping and Address applications:

Google Maps and Apple Maps-

In the realm of address management, Google Maps and Apple Maps,
while powerful for general navigation, encounter significant limitations when compared to the specialized TTPost Address Management System tailored for Trinidad and Tobago's unique S42 addressing system.

Unlike the TTPost system, Google Maps and Apple Maps lack access to the S42
database, rendering them unable to provide accurate and official S42 addresses.
Additionally, these global mapping giants lack a dedicated focus on official address management, resulting in the absence of features like requesting official address cards, a key component offered by the TTPost system.

Moreover, due to their reliance on various data sources, Google Maps and Apple Maps may experience delays in updating address information, potentially leading to outdated data and misinformed users. In contrast, the TTPost Address Management System ensures timely updates with accurate S42 address information, creating a more reliable resource for users, particularly those navigating the Trinidad and Tobago postal landscape. 

With the TTPost system's emphasis on data accuracy, official address services, and prompt updates, it emerges as a specialized solution catering precisely to the unique addressing needs of Trinidad and Tobago.
